Why fusion energy production does not solve environmental problems if our habits and attitudes do not change?

Solar energy is, in fact, fusion energy. Thus, if one were able to harness fusion for energy production, all our problems with fossil fuels and consecutive climate change would be just a bad dream. Throughout my life, it has been promised that harnessing nuclear fusion for energy production is 30 years away – hitherto it has been the longest 30 years ever recorded, as 55 years have gone, and the possibility of commercial application of fusion power is still 30 years away. Last week widely spread news item (based on successful experiment) suggests that this time the 30 years away may actually be 30 years away. If, and hopefully as, this is true, the energy production can become carbon neutral and the climate change combatted effectively with almost infinite source of energy.
It is possible that many people have already taken this news to mean that environmental actions are no longer necessary. This is largely because climate change has been the one and only environmental problem in the news. However, the fact is that even if the energy problem and its consequences to the environment become solved, we are still living in a planet with limits, and there is no planet B, where we could continue to spread. The real problem is the concept of growth. That is what we must continue to fight against even if the energy problems get solved.
Infinite growth is possible only if there are no limits. And already in 1970’s it became obvious to scientists that the earth has limits. At present man is using much more resources than there are available. Also, human land use is leaving less and less area to wild animals and plants with the consequence that the biodiversity of earth is diminishing. This leads, e.g., to increased likelihood of animal-to-human spread of diseases such as Covid 19. The pesticide and fertilizer use, which has the aim to increase agricultural production, is now starting to cause the opposite, as the pollinators and the beneficial soil microbes start to suffer. Further, the use of chemicals inevitably causes pollution.
So, even if fusion energy becomes available, we need to limit population growth, resource and land use, and stop pollution. One of the most important things for mankind is to realize that we should all think of ourselves as brothers and sisters regardless of if we live in Finland or Malawi, Russia or Ukraine, China or USA. Another thing to realize is that we should all be equal, the Putins, Musks, Trumps and Xis of the world should realize this.
